Explanation

Question 4 of 9

1

What is true about glycogen phosphorylase?

Select one of the following:

1.) Glycogen phosphorylase can only work in the non-reducing ends
2.) It will stop acting when there are 4 or less residues in a ramification
3.) Glycogen phosphorylase generates a molecule of Glucogen1P and a molecule of glycogen with a residue less from the degradation of a molecule of glycogen
Only 1.) and 2.) are true
All statements are true

Explanation

Question 5 of 9
